TUBULAR SPECIFICATION forming part of Letters Patent No. 572,949, datedDecember 15, 1896.

Application filed July 8, 1895. $erial No. 555,300. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES BERGENER, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Tubular Lanterns; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a part of this specification,and to the reference-letters marked thereon.

My present invention has for its object to provide an improved lanternparticularly adapted for use on railroads, and in which the globe isadequately protected from breakage and the lantern-frame strong enoughto sustain the shocks to which it is liable to be subjected, and onewell adapted for the burning of ordinary kerosene without liability ofbein g extinguished by high winds or shock; and to these and other endsit consists in certain improvements and combinations of parts, all aswill be hereinafter fully described, and the novel features pointed outin the claims at the end ofthis specification.

In the drawings, Figure l is a sectional view of a lantern constructedin accordance with myinvention, a portion of the upper part being shownin elevation; Fig. 2, a similar view taken at right angles to the planeof Fig. 1; Fig. 3, a horizontal sectional view with the globe removed;Fig. 4, a side elevation of the base, showing the globe-lifting device;Fig. 5, a horizontal sectional view on the line 00 a: of Fig. 1.

Similar reference-letters indicate similar parts.

The base of the lantern is composed of the ordinary oil-pot A, havingthe usual neck a, into which fits the slip-burner B, 0 indicating theair-chainber around the burner with which the tubes D communicate, and Ethe burnercone, fitting the top of the air-chamber.

F indicates the globe of the Ordinary type used in railroad-lanterns,resting upon the perforated globe-plate G. This globe-plate differs fromthe ordinary form in having the outer portion upon which the globe restsslightly depressed, forming a slight groove between the central part andthe peripheral bead or flange 9, preventing the globe from slippinglaterally when one side of said plate and the globe are elevated forlighting, as will be described, and it is also provided with anoperating'handle g, formed of a wire loop, passing around one of theguard-wires H.

Secured to the base of the lantern and extending upwardly therefrom arethe vertical guard-wires l-I, (preferably formed of doubled wires,)engaging a wire ring H at the upper end, and between this ring and thebase are arranged one or more horizontal wire guardrings H passingthrough the vertical guards forming a rigid and eflicient basket orguard for the globe not liable to be broken. Secured also to the topring H are the wire ears h, to which the bail J is attached in the usualmanner.

The upper or cover section of the lantern embodies a hood ordeflecting-plate K, hinged at 7.; to the ring 1-1 and fastened at theopposite side by the ordinary spring-catch K This plate K is providedwith a short collar K, and over it is arranged a dome L, with the lowerportion slightly flaring and projecting a slight distance below the topof the collar K, while its upper end is covered by a plate L, andbeneath said plate is aseries of perforations L for the escape of theproducts of combustion. A guide ring or flange M is arranged inside thedome, through which pro jects the upper end of the sleeve or hell N,having the flange a at its lower end and resting upon the upper end ofthe globe.

Between the flange n and the ring M is arranged a spiral spring Z,holding the globe pressed downward upon its plate, the motion of thesleeve being limited by a cross-pin O in the lantern-top passing throughtwo of the vertical slots P, formed in the sleeve. D D indicatetube-sections on opposite sides of the lantern connected to the dome andplate K, their upper ends entering the air-chamber Q, formed between thedome and sleeve N, while their lower ends are slightly larger than theupper ends of the tubes D and are arranged to receive them and make atight joint with them when the upper sect-ion is fastened down by thecatch.

R indicates short dividing-plates arranged H and also through theair-tubes D, the whole ICO in the air-chamber Q, and extendingvertically across the inner ends of the tube-sections D, their functionbeing to prevent the circulation of air around in the chamber Q and todirect a portion of the air entering said chamber from below into thetubes.

IV hen the lantern is lighted, the hot air and products will pass upthrough the sleeve N an d out laterally through the perforations L whilefresh air will enter through the perforated globe-plate and will also bedrawn'in from the chamber Q. by the downdraft in the tubes caused by therise of the air in the globe or chimney from the chamber beneath theburner. By this arrangement the extinguishment of the flame by highwinds or rapid movement of the lantern is prevented, currents, whichotherwise might extinguish the flame, being equalized in a manner wellunderstood by those skilled in the art.

When the lantern-top is closed, the springpressed sleeve N holds theglobe and globeplate down, and when desired to light the wick withoutopening the top the operator simply raises the handle'g on theglobe-plate, as in dotted lines in Fig. at, tilting said plate 011 theburner or the guard, if desired, raising the globe into the dome againstthe tension of the spring, leaving an aperture between the plate andglobe on the side opposite the handle sufficiently large for theilltroduction of a lighted match, which may be applied to the wick. I bypreference locate the handle substantially in line with the opening inthe burner-cone, so that the wick can be readily reached.

\Vhen it is desired to remove the globe to clean it or for any otherpurpose, the top section may be tilted back on the hinge, as shown indotted lines in Fig. 2. The perforated globe-plate will be preventedfromfalling out by reason of the connection of the handle g with one ofthe vertical guardavires.

The advantages of my construction, whereby a tubular railroad-lantern isprovided, will be obvious to those skilled in the art.

I claim as my invention 1.
